Pearson’s determination coefficients using the 95% confidence interval. TPC: total phenolics content, TFC: total flavonoids content, DPPH: DPPH scavenging activity assay, FRAP: Ferric reducing antioxidant power assay, TAC: total antioxidant capacity. The Pearson correlation coefficients (R2) between different parameters (p < 0.05) are shown in the statistical data.
